Quick Transmigration: The Supporting Character Is Always Forced into Love

An ordinary person's days of quick transmigration, filling in the background as an extra:

1. An extra in a sweet school romance

2. An extra in a domineering CEO novel

3. An extra in a strange world

4. An extra in a deserted-island survival story

5. An extra in a card-game world

6. An extra in a xianxia novel

7. An extra in a Western fantasy novel

8. An extra in a sci-fi novel

9. An extra in a novel about a reborn supporting female character

10. An extra in a period novel

That's all I've thought of so far, but there may be more later. One man and one woman, a 1v1 romance. I don't like angsty stories, so the heroine won't suffer abuse. She's not a strong, badass type, either, just an ordinary person with ordinary thoughts and limited experience. She may grow as she transmigrates, but she never expects to become the strongest. The hero is split into multiple versions. After one version is influenced by her, it sets off a domino effect, and all the other versions fall in love with her.

This novel and its characters are entirely fictional. Any resemblance to real people or events is purely coincidental. Do not imitate.
